Method of manufacturing tamper evident package

Abstract

A method of making a resealable package is provided. The method comprises providing an assembly that has a header section and a closure mechanism comprising first and second closure profiles constructed and arranged to selectively interlock. The method further includes providing a package comprising first and second panel sections joined together to define an enclosed region, first and second opposite side edges, a bottom and a mouth that provides access to the enclosed region. Finally, the method comprises attaching the assembly to the package such that the header section is attached to the closure mechanism at a point between the closure profiles and the bottom of the package.

What is claimed is:  
     
         1 . A method of making a resealable package comprising: 
 (a) providing an assembly comprising: 
 (i) a header section;  
 (ii) a closure mechanism comprising first and second closure profiles; 
 (1) the first and second closure profiles constructed and arranged to selectively interlock;  
 
   (b) providing a package comprising: 
 (i) first and second panel sections joined together to define an enclosed region, first and second opposite side edges, a bottom and a mouth that provides access to the enclosed region; and  
 (ii) attaching the assembly to the package such that the header section is attached to the closure mechanism at a point between the closure profiles and the bottom of the package.  
   
     
     
         2 . The method of  claim 1 , wherein the header section comprises two sides joined together to define first and second mouths, the first and second mouths being in fluid communication with each other.  
     
     
         3 . The method of  claim 2 , wherein the step of providing the assembly comprises sealing a portion of the two sides together.  
     
     
         4 . The method of  claim 3 , wherein the seals are formed in a pair of mirror-image L-shapes.  
     
     
         5 . The method of  claim 4 , wherein the step of providing the assembly further comprises removing the portions of the header inside of the L-shaped seals.  
     
     
         6 . The method of  claim 2 , wherein the header section includes a preferential area of weakness.  
     
     
         7 . The method of  claim 6 , wherein the area of weakness is produced by scoring the header section.  
     
     
         8 . The method of  claim 6 , wherein the preferential area of weakness includes at least one notch cut into the header section.  
     
     
         9 . The method of  claim 2 , wherein the two sides are formed by folding a single sheet of header material in half, and the second mouth is formed by eliminating a portion of the header material around the fold.  
     
     
         10 . The method of  claim 1 , wherein step of providing the assembly comprises sealing the header section to the flanges of the closure mechanism.  
     
     
         11 . The method of  claim 10 , wherein the step of sealing the header section comprises 
 (a) separating the first and second closure profiles;    (b) placing a portion of the header section between the first and second closure profiles;    (c) attaching the slider to the closure mechanism;    (d) notching the closure profile at one end, the notch to be used as a park position for the slider; and    (e) applying a stop seal to at least one end of the closure mechanism.    
     
     
         12 . The method of  claim 1 , wherein the step of attaching the assembly to the package comprises heat sealing the closure profiles to the two opposing panels.  
     
     
         13 . The method of  claim 12 , wherein the step of attaching the assembly to the package further comprises sealing the sides and bottom of the two opposing panels together.  
     
     
         14 . The method of  claim 1 , further comprising filling the package with a product through the first mouth of the header section.  
     
     
         15 . The method of  claim 1 , further comprising sealing the first mouth of the header section.  
     
     
         16 . A header and closure mechanism assembly for use in a resealable package consisting essentially of: 
 (a) a closure mechanism comprising first and second closure profiles, the first and second closure profiles constructed and arranged to selectively interlock; and    (b) a header section comprising two sides joined together defining first and second mouths, the first and second mouths being in fluid communication with each other, the header section being attached to the closure mechanism.    
     
     
         17 . The assembly of  claim 16 , further consisting essentially of a slider attached to the closure mechanism.  
     
     
         18 . The assembly of  claim 17 , wherein the closure mechanism defines a notch near one end of the closure mechanism.
